The price of Bitcoin is highly volatile due to which the government of a country neither encourages nor forbids its people to invest in it. Bitcoin usage and investment is entirely up to you. Bitcoin is a legal currency in many countries and anyone there can use Bitcoin and accept it in exchange. But it is entirely at his own risk. In the future, the use of Bitcoin will probably increase even more. However, one cannot exclude the use of FIAT money. FIAT money is money authorized by the individual government of a country. It must always be in vogue
High volatility is not the main reason why governments make bans, as I said before, they just don't want Bitcoin to be popular and always used in those countries, actually it doesn't matter to them if Bitcoin can be controlled, the problem is that Bitcoin cannot be controlled. So we can assume that the main reason governments ban Bitcoin is because Bitcoin cannot be controlled or is decentralized.
